Find the value of x.

Help ASAP will give brainliest

Answer:

y = 2x - 3

Yes, your answer is correct.

Step-by-step explanation:

First, find the slope of the two points by using the slope formula:

        y2 - y1

m = -------------

        x2 - x1

         13 - 5

m = -------------

          8 - 4

         8

m = ------- = 2

         4

To find the y-intercept, plug in values into the slope-intercept formula:

y = mx + b

Where m = slope and b= y-intercept. Use any one of the points. I'll be using (4,5):

5 = (2) (4) + b

5 = 8 + b

-3 = b

b = -3

So, putting everything into the slope intercept formula:

y = 2x - 3

Step-by-step explanation:

Joan wants to buy a new TV that costs $1299.99. The store has a discount on the TV for 30% off. The city Joan lives in has a 12.5% sales tax. What will be the total cost of the TV?

Step 1

We find the new price after the discount.

Discount = % Discount × Current price

= 30% × $1299.99

= $389.997

The new discounted price =

$1299.99 - $389.997

= $909.993

Step 2

We calculate the Sales tax

The city Joan lives in has a 12.5% sales tax.

Hence,

The sales tax =

12.5% × $909.993

= 12.5/100 × $909.993

= $113.749125

Step 3

The total cost of the TV is calculated as:

Sales Tax + Discounted price

= $113.749125 + $909.993

= $1023.742125

Approximately = $1023.74

The total cost of the TV = $1023.74

Answer:

43

Step-by-step explanation:

Since right angles are 90 degree. 90 - 47 = 43

It looks mirrored, so I am guessing the 47 degree is also at the bottom.

If I'm wrong, I apologize.

The box office sold 360 tickets to a concert at

the college. The total receipts were $4,170. General

admission tickets cost $15 and student tickets cost $10.

How many of each kind of ticket was sold?

Answer: 114 general admission tickets and 246 student tickets were sold.

Step-by-step explanation:

Let x represent the number of general admission tickets that were sold.

Let y represent the number of student tickets that were sold.

The box office sold 360 tickets to a concert at the college. It means that

x + y = 360

General admission tickets cost $15 and student tickets cost $10. The total receipts were $4170. It means that

15x + 10y = 4170- - - - - - - - -1

Substituting x = 360 - y into equation 1, it becomes

15(360 - y) + 10y = 4170

5400 - 15y + 10y = 4170

- 15y + 10y = 4170 - 5400

- 5y = - 1230

y = - 1230/-5

y = 246

x = 360 - y = 360 - 246

x = 114

Answer:

Step-by-step explanation:

Subtract 2nd equation from the first

53b+94g-53b-47g=4482-3354

47g=1128

g=24, using this value in 53b+94g=4482 gives you

53b+94(24)=4482

53b+2256=4482

53b=2226

b=43

So general admission tickets cost $24 and balcony tickets cost $43.

Answer: 468.75

is ya answer

i think

sorry if im wrong

Answer:

468.75

Step-by-step explanation:

First we need to add 25% to 500.00 which is 625.

Next we need to subtract 25% from 625.

Now we have 468.75.

The selling price of the couch is $468.75.

Answer:

Yes, but can be simplified to [tex]-\frac{1}{4}[/tex]

Step-by-step explanation:

Since slope is the formula to determine the equation of a line, we use,

[tex]\frac{rise}{run}[/tex]

In this sense, we can see that the rise is -2

The run, or how far along the x-axis the line goes until it reaches its desired point is 8.

Although you are correct in the [tex]-\frac{2}{8}[/tex], don't forget to use your GCF to determine how low the fraction can go. (GCF or greatest common factor of 2 in this case) to get [tex]-\frac{1}{4}[/tex]

I hope this answer finds you well, and I would be happy to help you again in the future! :D

Answer:

441[tex]\pi[/tex] inches squared i think

Step-by-step explanation:

radius = 42/2 = 21 inches

area = [tex]\pi[/tex] x [tex](21)^{2}[/tex]

area = 441[tex]\pi[/tex]

area = 1385.44236

5 1/3 is 64/12 in it's simplest form as a mixed number.

Answer: you got to Find the focus of a parabola given its equation. If you have the equation of a parabola in vertex form , then the vertex is at and the focus is . Notice that here we are working with a parabola with a vertical axis of symmetry, so the -coordinate of the focus is the same as the -coordinate of the vertex.

Step-by-step explanation:

Answer:

The shorter piece is 39 inches long.

Step-by-step explanation:

ratio = 3 : 1

3+1=4

156/4 = 39

just to check:

39 x 3 = 117 (the lenght of the longer piece)

117 + 39 =156

Answer:

  side = 20 cm

Step-by-step explanation:

We assume the two given lengths are sides of the square, so are equal to each other.

  6x -1 = 4x +6

  2x = 7

We could find x = 3.5, but we can use 2x, too.

  (2)(2x) +6 = 2(7) +6 . . . find the side length

  4x+6 = 20 . . . . the side length of the square
